There are mounting signals that Donald Trump's much-delayed Middle East peace plan – billed as the "deal of the century" – is about to be unveiled.

Even though Trump's officials have given away nothing publicly, the plan's contours are already evident, according to analysts.

They note that Israel has already started implementing the deal – entrenching "apartheid" rule over Palestinians – while Washington has spent the past six months dragging its heels on publishing the document.

"Netanyahu has simply got on with deepening his hold on the West Bank and East Jerusalem – and he knows the Americans aren't going to stand in his way," said Michel Warschawski, an Israeli analyst and head of the Alternative Information Centre in Jerusalem.

"He will be given free rein to do what he likes, whether they publish the plan or, in the end, it never sees the light of day," he told Middle East Eye.
